She wanted to "pass high" for the sake of Matthew and Marilla--especially Matthew.
Matthew had declared to her his conviction that she "would beat the whole Island." That, Anne felt, was something it would be foolish to hope for even in the wildest dreams.

But she did hope fervently that she would be among the first ten at least, so that she might see Matthew's kindly brown eyes gleam with pride in her achievement.

That, she felt, would be a sweet reward indeed for all her hard work and patient grubbing among unimaginative equations and conjugations.
At the end of the fortnight Anne took to "haunting" the post office also, in the distracted company of Jane, Ruby, and Josie, opening the Charlottetown dailies with shaking hands and cold, sinkaway feelings as bad as any experienced during the Entrance week.

Charlie and Gilbert were not above doing this too, but Moody Spurgeon stayed resolutely away.
"I haven't got the grit to go there and look at a paper in cold blood," he told Anne.

"I'm just going to wait until somebody comes and tells me suddenly whether I've passed or not." When three weeks had gone by without the pass list appearing Anne began to feel that she really couldn't stand the strain much longer.
